MW4530慎刷OpenWrt固件

679***

昨天刚到4530，刷写了4310的openwrt固件，结果发现无法启动
后又合成了4310，4300的编程器固件写入，均能正常启动
仔细分析op日志，发现是4530用了m25Q64闪存，而官方openwrt是没有这个驱动的
西面附上ttl，红色部分即为出错信息，暂时没编译环境
有兴趣的可以试下修改
drivers/mtd/devices/m25p80.c
增加箭头所示内容重新编译

不识别芯片不足以导致系统启动不了吧

支持一下。根目录在哪里啊drivers/mtd/devices/m25p80.c

laoy***

好不容易找到目录了。

好不容易找到目录了。

目录都找不到还怎么编译呀？

savi***

估计ls那个是去找路由器的目录。我今晚回去试试编译一个固件出来。

没太搞懂，继续思考。

看不懂，天书啊，纯顶

怎樣找这个目錄修改？？
